To an whom it may concern:

Be it known that I, CHARLES W. COOPER, a

in the Manufacture of Glue, of which thefollowing is a specification.

- My invention relates-in general to operations connected with the" formation of glue into sheets of jelly,.in which liquid glue fed upon the surface of acoolingcylinder is con-.

'gealed .thereuponinto a sheet which isthenstripped from the'cylinder, and then, usually,

'cut or divided into sections which=aresucycessively deposited upon carrying nets caused to travelibeneath the cooling cylinder off to" a drying room wherein the 'glue'isdried upon thenets. q V o. My-inventionrelates particularly to means I z 5- and delivering'device iniwhich acylindriform.

inder and by its positive rotationto strip the My present improvement contemplates the stripping of the sheet from the cooling cylinder bypassing it over an. idly-running roller axially parallel with the cylinder, and utilizing the weight of the advance end portion of the sheet pendent from'the roller to occasion the rotation. of the rollerand the stripping of the sheetfrom the surface of the cylinder.

, The sheet of glue, as will be apparent from an inspection-of the dr'awingsyis conducted from the cooling cylinder overand-in bite around the surfaceof the idler roller 0, and

is: thence carried to andvover the surface-of: a roller, which I term a directing roller D,'and which is but a type of asheet-directing deand at such distance from the idler-roller' as to'permit of the sag ofthesheet between said organized to be operative in'conj unction with cutting mechanism and traveling nets, the.

sections adapted to be successively deposited upon successive nets caused to travel beneath Y the cutting mechanism. The relative dispo sition of the parts is such that the weight of that length of sheet which is. extended and pendent between the idler roller and the directing roller, or its equivalent directing de vice, is sufficient not only to occasion the revo-j,

lution of the idler roller but to occasion also such sufficient tension in the portion of the sheet existing between the cooling cylinder and the idler roller as to strip the sheet from. "the cylinder. In-fact, the uppe'rpart of the sheet includingthatlengthWhich is bent about the idler roller will be stretched by the weig'ht of the pendent length beyond it, and

willcause-the idler roller to take on" a pevice,=located preferablyiupon a-lower level f Y rollers-from which, when theapparatusis l ripheralspeed corresponding with the stretch, I

and therefore a speed superior to that of-the surface'of the cylinder.- The directing roller I 1). maybe an idleora driven roller, or, if-desired, the particular take-up roller described and claimed in a pending application filed by me the 16th day of'April, 189-1, as Serial N o. 507,695.' When the apparatus isso organized that the sheet depends almost perpendicu cutting mechanism should be such that the length of sheet depending from it will possess suflicient weight to overcome the tendency of the advance end of the sheet, when cut, to slip backward over said directing roller.

In the frame E are contained a fixed cutting blade e and a movable cutting blade 6",- which latter is conveniently intermittently operated by cranks e, pivoted at e in the frame work, provided with counterweighted arms a to return them after deflection to their normal position, and connected by links 6 to said movable blade. These cranks are adapted to be encountered and deflected by the end bars f of glue-carryin g nets F, which are caused by any preferred means to travel along suitable conveyer-ways.

I have not deemed it necessary to illustrate in the drawing conveyer-ways,or means for occasioning the travel of the nets or the rotation of the cooling cylinder, as these means may be such as the convenience of the constructor may dictate. In fact, my invention deals particularly with the stripping of the sheet from the cooling cylinder by the utiliza tion of the weight of the advance end of the sheet depending from an idler roller located in proximity to the cylinder over which said sheet is led.

Having thus described my invention, I claim- 1. In an apparatus for the manufacture of glue the following elements in combination a feed for liquid glue,a revoluble cooling cylinder upon the surface of which liquid glue is delivered and congealed into a sheet of jelly,--and an idler roller over which the sheet is led from the cylinder and which is revolved to occasion the stripping of the sheet from the cylinder by the weight of the advance end of the sheet depending from it,- substantially as and for the purposes set forth.
